Using the History Object to Go to Specific Pages

Question:

I am using history objects back(1) ( history.back(1) )method in my HTML application to go to previous screen and it is working alright but I am not able to go back to a second previous screen . I have tried history.back(2), history.back(3), and so forth but it is not working.
